Abstract

Abstract: PURPOSE: To develop a novel microsurgical training tool based on 3D printed hydrogel and evaluate its practicality and teaching effectiveness. METHODS: A series of micro-vessels were designed and produced with hydrogel by 3D printing technology and were loaded into a piping connection system with pump and other components to compose a set of microsurgical training tool; then 10 senior microsurgeons who had rich clinical teaching experience in microsurgery were selected to evaluate the differences between this new teaching aid and the traditional teaching instruments by questionnaire. Another 24 interns who were in the 5th year program of stomatology were randomly divided into the control group and the experimental group. The interns in the control group were trained for anastomosis skill twice a day by traditional instrument for 10 days, while the interns in experimental group were trained by the novel teaching tool. Then the two groups of students were given a test of microsurgery skill by doing anastomosis with rat carotid artery. Each intern's capacity of microsurgery was scored to compare the effectiveness of this novel teaching tool with the traditional one. The data were analyzed with SPSS 19.0 software package. RESULTS: A set of novel microsurgery training aid with 3D printed hydrogel blood vessels as the core was developed. The questionnaire results of 10 senior microsurgeons showed that this new teaching aid was more practical, scientific and effective than the traditional one. The score of the interns in the experimental group was significantly higher than that of the control group (P< 0.05). CONCLUSIONS: This set of teaching aid for microsurgery based on 3D printing hydrogel vascular technology is highly practical, scientific in design, convenient in use and economic in cost. Its effect in actual clinical teaching practice of microsurgery is obviously better than the traditional teaching model, indicating that this novel teaching aid is convenient for standardized training and worthy of wide application.
